It is stored in the channel image data storage area 44, the b channel image data storage area 45, the enlarged image data storage area 41, and the masking image data storage area 42, respectively. Image data representing an image in the selection area A is stored in the selection image data storage area 33. These image data are stored in the order of relative addresses of the corresponding areas according to the order of horizontal and vertical scanning.

Windows W1, W2, W3, W4, W5
The position coordinates of W6 and W6 on the display screen (for example, the coordinates of the upper left corner of each window) are (x1, y1), (x2, y2), (x3, y3) as shown in FIG.
), (X4, y4), (x5, y5), and (x6
, Y6). Therefore,
The image data read from these storage areas are displayed by converting their addresses into coordinates on the display screen (stored in VRAM, for example) by the display controller 25 using the position coordinates of each window. .

The data representing the boundary line is composed of a row of coordinate data of dots (pixels) on the display screen representing the boundary line. This data is also stored in a predetermined area of the storage device. Since the position coordinates of each window are predetermined as described above, the coordinate data string representing the boundary line specified in one window is easily converted into the coordinate data string in another window.

The image enlargement process is performed as shown in FIGS. For example, when the image is doubled (in the vertical or horizontal length), data having the same value as the original image data of one pixel is assigned to four pixels at corresponding positions. This is performed, for example, when the images in the selected area are displayed in windows W1 to W3. When the image is enlarged three times (in the vertical or horizontal length), data having the same value as the original image data of one pixel is assigned to each of the corresponding nine pixels. This is performed, for example, when the images in the selected area are displayed in windows W5 and W6.

However, when the original image data is thinned out (for example, the image is reduced to 1/2) and displayed in the whole image display window W1, windows W2 to W2
In 4, the original image data can be used as it is.

FIG. 4 shows an initial screen window Wo displayed on the initial screen of the monitor display device 50. In the initial screen window Wo, a composite image window Ws for displaying a composite image is displayed in a region on the substantially left half thereof. An almost right half area of the initial screen window Wo is a button display area BA for setting image data processing. In the button display area BA, there are a cutout button B1 that is clicked when cutting out an image, a paste button B2 that is clicked when pasting an image cut out to generate a composite image on a background image, and a cutout image. A background selection button B3 clicked when selecting a background image to be combined is included.

When the cutout button B1 is clicked by the mouse 11, a cutout window W for generating a cutout image shown in FIG. 5 appears on the display screen of the monitor display device 50.

Subsequently, the original image data stored in the original image data storage area 31 is read out, and the monitor display device 50
Image is displayed on the whole image display window W1 as shown in FIG.

Further, the mouse 11 is used to designate the selection area A on the whole image display window W1. When the selection area A is designated, image data representing the image in the designated selection area A is extracted from the original image data, L, a, b conversion, enlargement processing and masking processing are performed, and these data are It is temporarily stored in the storage areas 43, 44, 45, 41 and 42.

By being given to 50, an image in which a boundary line indicated by a chain line is displayed as shown in FIG. 8 is displayed on the monitor display device 50.

Thus, the whole image display window W1
The boundary line traced by the tablet pen 12 above and displayed in the selection area A is also displayed in the other windows W2, W3, W4, W5 and W6 corresponding to the selection area A. When different locations in the selection area A are traced by the tablet pen 12 on the whole image display window W1, the storage areas 31, 41, 42,
The image data stored in 43, 44, and 45 are processed so that the displayed border line moves, whereby the other windows W2, W3, W4, W5 corresponding to the selected area A are processed. The boundary line displayed at and W6 also changes. Thus, the whole image display window W
Boundary line on 1 and other windows W2, W3, W
4, border lines on W5 and W6 are displayed correspondingly. The black-painted portion in the mask image display window W6 is enlarged or reduced in accordance with the change in the display of the boundary line on the entire image display window W1.

The subject image displayed in the whole image display window W1 is relatively small. Therefore, using the tablet pen 12, the whole image display window W1
Even if the boundary line of the cut-out portion on the subject image displayed above is specified, it is not possible to accurately specify the fine portion. In such a case, a boundary line is designated on the enlarged image displayed in the enlarged image display window W5.

Referring to FIG. 9, when the enlarged image displayed in enlarged image display window W5 is traced with tablet pen 12, the position of the boundary line in enlarged image display window W5 moves to the traced position. The boundary lines displayed in the other windows W2, W3, W4 and W6 and the whole image display window W1 are also displayed while being moved in correspondence with the boundary line of the window W5.

Since the image displayed in the enlarged image display window W5 is the largest of the images showing the selection area A, even if the boundary line is specified using the tablet pen 12, the boundary line is relatively easy. Can be specified.

Further, of the image displayed in the masking image display window W6, the part other than the image to be cut out is blackened with the tablet pen 12.
The boundary line may be specified accurately. Even in this case, the boundary lines displayed in the other windows W2, W3, W4 and W5 and the whole image display window W1 according to the movement of the boundary line in the mask image display window W6 also correspond to the masking process of the window W6. Then it is moved and displayed.

In the masking process, the boundary of the image portion to be cut out can be designated relatively easily as if it were a coloring page.

As described above, in addition to the whole image display window W1, the L channel image display window W2, the a channel display window W3, the b channel display window W4,
When the boundary line is moved on the images displayed in the enlarged image display window W5 and the mask image display window W6, the boundary data existing in the boundary line in the selected area A among the boundary data stored in the boundary data storage area 33. Is corrected, and a boundary line is displayed at a position corresponding to the position of the moved boundary on the display screen of each of the windows W1 to W6.

The boundary line of the portion to be cut out is specified using the tablet pen 12 on the subject image displayed in the whole image display window W1, the selection area A is moved to the portion to be cut out, and the enlarged image display window W5 is displayed if necessary. For example, specify the boundary of the cut portion more accurately. When the accurate specification of the boundary line of the cutout portion in the selected area A is completed, the mask 12 moves the selected area A to another cutout portion, and the accurate specification of the boundary line of the cutout portion is repeated.

Depending on how the light hits the subject, RGB
When an image based on the image data is displayed on the monitor display device, the edges may not be clearly displayed and may be blurred. In such a case, the boundary line of the image portion to be cut can be accurately specified and displayed on the window. For example, in the portion of the original image designated in the selected area A shown in FIGS. 7 to 9 depending on how the light hits the subject, the edge appears accurately even in the image represented by the RGB data. In the portion of the subject image designated in the selection area A shown, the edge may not appear accurately in the image represented by the RGB data. However, even if an edge does not appear accurately in an image represented based on RGB image data, an edge may appear accurately in an image obtained by converting chromaticity coordinates of RGB image data. In this case, the boundary is accurately specified using the L channel image display window W2, the a channel image display window W3, or the b channel image display window W4.

Referring to FIG. 11, when the selection area A is designated on the whole image display window W1 with the mouse 11, enlarged images corresponding to the image of the selection area A are displayed in the windows W2, W3, W4 and W5. And W6. Even for the images displayed in these windows W2, W3, W4, W5 and W6, the images in the windows W5 and W6 displayed based on the RGB data are blurred depending on how the light hits the subject. ，
It may not be possible to specify an accurate border line. However, in any one of the L channel image, the a channel image, and the b channel image in which the RGB image data is converted and displayed with chromaticity coordinates, the image may not be blurred and the edges may be displayed properly.

In FIG. 11, windows W2, W4, W
In 5 and W6, the image corresponding to the selected area A is blurred (the degree of blurring is indicated by the fineness of hatching, and the wider the hatching, the more blurred the image is. Indicates that the narrower the image is, the less blurred it is.), And the a-channel image represented by the a-channel converted data is displayed without blurring.

In such a case, as shown in FIG. 12, the boundary line is designated by using the tablet pen 12, and the enlarged image window W5 or the masking image window W5 is displayed.
Even if an attempt is made to move the boundary line to an accurate position using 6, it is difficult to specify the position of the boundary line accurately because the image displayed in the window W5 or W6 is blurred. Therefore, in this case, the boundary line is accurately specified using the image displayed in the a channel image display window W3 (see FIG. 13).

When the boundary line is moved by tracing over the a channel image display window W3 using the tablet pen 12, it is displayed in the selection areas of the other windows W2, W4, W5 and W6 and the whole image display window W1. The boundary line moves correspondingly as in the case described with reference to FIGS. 7 to 9.

As described above, the entire image display window W is first displayed.

The background image data representing the selected background image stored in 35 is read, and the read clipped image data and the background image data are combined. The synthetic image data obtained by the synthesis is given to and stored in the synthetic image data storage area 37. The combining process is performed so that the positional relationship between the background image and the cutout image is appropriate.

The composite image data stored in the composite image data storage area 37 is read out, given to the frame memory 24, and temporarily stored. The composite image data shown in FIG. 17 is obtained by reading the composite image data from the frame memory 24 and supplying it to the monitor display device 50 via the display control device 25.
It is displayed in the composite image display window WS shown in FIG.

In the combined image shown in FIG. 17 obtained when the cutout image shown in FIG. 15 and the background image shown in FIG. 16 are combined, the area AS is not included in the cutout image. Therefore, for this area AS, among the color data stored in the color data storage area 36 of the storage device 23, a color close to the color of the clipped image near the area AS (for example, flesh color data is read). And the image is replenished as an image of the area AS, thereby obtaining a natural composite image.

18 and 19 show another example of the clipped image window displayed on the monitor display device.

In the clipping image window Wc shown in FIGS. 18 and 19, the clipping image window Wc
